If a bar magnet is gradually rotated about its center through 180 degrees, its north and south poles will effectively switch places. This change in orientation will not affect the magnetic field's strength or shape; however, the direction of the magnetic field lines will reverse. Thus, the magnet will still exhibit the same magnetic properties, but in the opposite direction. Overall, the magnet's behavior in an external magnetic field or interaction with other magnets will also be altered accordingly.
What else can I help you with?
Can magnet pass through wood?
yes it can
How do you strengthen a magnet?
You can strengthen a magnet by exposing it to a strong magnetic field, either by placing it near another strong magnet or using an electromagnet. You can also induce a current in the magnet by tapping it with a hammer or passing an electric current through it to realign its magnetic domains and increase its strength.
How can the magnetism of a permanent magnet be weakened or removed?
Put it in a coil which has an alternating current in it. The AC current produces a magnetic field in the coil which alternates with the changing voltage. This changes the magnetism of the permanent magnet. Gradually reduce the current in the coil and the permanent magnet will end up unmagnetised.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
How alternating voltage is generated in a coil of wire when it is rotated between the poles of a magnet?
Electical current.=============================Answer #2:When a coil moves in the vicinity of a magnet, a voltage between the endsof the coil is produced. If the coil happens to be part of a closed circuit, thenthere could be an electrical current.Answer #3When a coil moves through a changing magnetic field, a voltage is produced, and when a resistor is connected to the coil some current flows and power is produced in the resistor. This power comes from the mechanical power needed to push the coil through the magnetic field when it carries a current.
Is it true that the magnetic force becomes stronger towards the centre of the magnet?
No.The part of the magnet where there is the strongest pull or attraction are called the poles of the magnet.
What has happened if a magnet becomes barely magnetic?
There are things (I can't remember their name) that face in one direction on a magnet. When these face in different directions the magnet gradually loses force
Where do you use magnet to generate energy?
Magnets are used in generators to convert mechanical energy into electrical energy. When a magnet moves near a coil of wire, it induces an electric current in the wire through electromagnetic induction. This current can then be harnessed as electricity for various applications.
Name two things that a magnet force can pass through?
what are the things pass through magnet fields?
Can magnet pass through wood?
yes it can
How many sheets of paper can a magnet pull through?
The number of sheets a magnet can pull through will vary depending on the strength of the magnet. Generally, a typical refrigerator magnet can pull through a few sheets of paper, while a more powerful neodymium magnet could potentially pull through a thicker stack of papers.
What is a magnet that is creadted from electric current through a wire?
Electro-Magnet
What a moving magnet makes?
makes current flow through a magnet
What produces an electric current when a coil of wire is wrapped around an iron core is rotated near a magnet?
This phenomenon is known as electromagnetic induction. When the coil of wire is rotated near a magnet, the changing magnetic field induces an electric current in the wire due to Faraday's law of electromagnetic induction. The iron core enhances the magnetic field, resulting in a stronger induced current.
What is the region around a magnet where the magnetic force is exerted at?
The region around a magnet where the magnetic force is exerted is called the magnetic field. This field exists in three dimensions and is strongest closer to the magnet, gradually weakening as you move away.
How does the ball stay still in centre for start of water polo?
by magnet on a string and held down by a weight
What happens when a strong electric field is passed through a permanent magnet?
The electrons of the permanent magnet would align the way the electromagnetic field passed through the magnet.
